我正在使用 git.sh这链接，我有密钥文件：
sh-3.2# ls -al /Users/tiina/.ssh/id_rsa/
drw------- 4 tiina en 136 Jun 18 19:26 .
drwx------ 5 tiina en 170 Mar 15 2016 ..
-rw-------@ 1 tiina en 1482 Jun 18 19:19 pri_rsa.ppk
但是当我在 Mac 上运行时
./git.sh -i ~/.ssh/id_rsa/pri_rsa.ppk clone ssh://[email protected]:2222/foo
Cloning into 'portal'...
Warning: Identity file /Users/tiina/.ssh/id_rsa/pri_rsa.ppk not accessible: Permission denied.
Load key "/Users/tiina/.ssh/id_rsa": Is a directory
Permission denied (publickey).
fatal: Could not read from remote repository.
Please make sure you have the correct access rights
and the repository exists.
编辑：事实证明我在这里犯了两个错误。在 mac 中使用 ssh 时，应先将私钥从 ppk 转换为 pem：
puttygen xxx.ppk -O private-openssh -o xxx.pem
（首先使用安装腻子sudo brew install putty）
答案1
chmod u+x /Users/tiina/.ssh/id_rsa/
